JUAN FERNANDEZ KNOCK, OFLEWISTOWN, ILLINOIS.

FUEL-SAVER.

Application filed August 8, 1918.

America, residing at Lewistown, in the county of Fulton and State ofIllinois, have invented new and useful Improvements in Fuel-Savers, ofwhich the following is a specification.

The purpose of the invention is to provide means to be used inconjunction with heating apparatus whereby the products of combustionare required to pass over a tortuous path to the chimney, there beingdevices associated with the said means, so that the heat radiated by thesaid products of combustion may be conserved and conducted to pointswhere it is desired to utilize the same.

A further purpose of the invention resides in the provision of a fuelsaver which is comparatively simple in construction, durable andeffective in operation and inexpensive to manufacture and place on themarket.

Other and further purposes of the invention appear in the. followingdescription wherein the same is set forth in detail.

To the exact construction in which it is shown and described, theinvention is not to be restricted. make any changes or alterations thatthe actual reduction to practice may suggest, provided these changes andalterations are compatible in spirit with the subjoined claim.

The figure is a View partly in section and,

The invention is shown applied to the ordinary heating stove 1 carriedupon the floor 2 which is presumed to be the floor of the room which thestove is intended to heat. Between the stove and the chimney 3, there ispositioned a casing 4. having the shape preferably of a rectangularparallelepiped. On the interior this casing 1 is divided intocompartments 5, 6, 7 and 8, the compartments 5'and 7 being accessible tothe doors 9 and 10. The compartments 5, 6 and 7 are formed in asupplemental casing 11 carried interior to the casing 4.

The pipe 12 through which the exhaust gases pass on their way to thechimney 3 is provided with a down leg 13 which passes through the top ofthe casing 4 adjacent that end nearer the stove 1 and this downSpecification of Letters Patent.

The right is claimed to- Patented Sept. '7, 1920'.

leg communicates with the compartment 5 through the top of the casing11. Interconnecting the compartments 5 and 6 there is a tubular U-shapedmember lt and a similar member 15 interconnects the compartments 6 and 7from the latter of which there rises a pipe 16 which passes through thetop of the casing i and connects with the chimney 3, a damperl? beingcarried in the horizontal leg of this pipe 16.

Connected with the top of the casing 4 and preferably adjacent thecenter of the latter, there are the pipes 18 which communicate with thecompartment 8 of the casing.

In the operation of the invention, the products of combustion such assmoke and burnt gases pass through the pipe 12 and its down leg 13 intothe compartment5, thence through the tubular member 14 into thecompartment 6, thence through the tubular member 15 into the compartment7 from which last compartment they pass through the pipe 16 and throughthe chimney 3 to the atmosphere. In this circuitous or tortuous path ofthe gases, the heat that is contained in them is radiated through thedown leg 13, the tubular members 14 and 15 and the pipe 16 and a verylarge percentage of this heat radiation takes place in the compartment 8from which this trapped or confined heat may pass through the pipes 18to any part of the house it is desired to use the heat, the pipes 18, ofcourse, being led to the points where it is desired to utilize the heat.

The invention having been described, what is claimed as new and usefulis:

In a fuel saver, the combination with a heating unit, of a main casing,a supplemental casing interior to the main casing and divided into aplurality of compartments, tubular connections between the compartmentsof the supplemental casing, a

tubular connection between the heating unit and one of the compartmentsof the supplemental casing, another of the compartments of thesupplemental casing having means for connection to a smoke stack,certain of the tubular connections and portions of the others beinginclosed wlthin the main casmg, and tubular members communicating withthe main casing for the purpose specified.

In witness whereof he affixes his signature.
